Hi Guys;
      Paul not a problem, planned on using a fuel cooler
regardless, (Had to "dead stick it in" once due to fuel
vaporising, been using one ever since, cheapest
insurance to have)  My question now is: What constitutes
a safe fuel temperature range/target?

Ed......Have you taken fuel temperatures during extended
idling? If not could you?
How hot does it get where you commonly use this system?
75 hrs. over what period?
                                Thanks...Butch Diaz Sr.

 Butch,

    Good idea on the fuel cooler.  Where did you find one?

    No, I've not taken fuel temperatures.  I don't see why I could not take
the temperature of the fuel in the header tank.   In fact I probably could
remove the fuel drain on the bottom of header tank and stick the temp probe
there as the fuel is pulled by the EFI pumps draws from near the bottom of
the header.  Could drill out an NPT fitting for a temp probe and perhaps
hook it up to my water temp gauge in the cockpit to get readings.  .

  I might be a little while as I am currently swapping my six port 13B for a
87-88 Turbo II with 89 Rotors and doing a few other things to get me back
into the air.  I had one apex seal stuck on the six port 13B that I could
not get unstuck, so took the opportunity to swap engines.

Temp in the summer gets into the high 90Fs, but seldom goes over 100F, but
the high humidity also adversely effects cooling scenario.

Flew 72 hours last year and only 2.5 this year thus far.
